The reason is that in 3.x Python You can’t just mix unicode strings with byte strings. Probably, You’ve read the manuals dealing with Python 2.x where such things are possible as long as bytestring contains convertable chars. works fine for me, so the only reason is that you’re using wrong encoding for source file or … Read more
I’m getting a compile error at the following method. at Utility.java:[76,74] unmappable character for enoding UTF-8. 74th character is’ ” ‘ How can I fix this? Thanks.
Works for me, when I copy/paste your code. Try replacing the double quotes in your str_replace() with single quotes, or escaping the backslash (“\\u00a0”).
To expand on the answers others have given: We’ve got lots of languages with lots of characters that computers should ideally display. Unicode assigns each character a unique number, or code point. Computers deal with such numbers as bytes… skipping a bit of history here and ignoring memory addressing issues, 8-bit computers would treat an … Read more
It’s called percent encoding. Some characters can’t be in a URI (for example #, as it denotes the URL fragment), so they are represented with characters that can be (# becomes %23) Here’s an excerpt from that same article: When a character from the reserved set (a “reserved character”) has special meaning (a “reserved purpose”) in a certain context, … Read more
Yes, it is also a comment. And the contents of that comment carry special meaning if located at the top of the file, in the first two lines. From the Encoding declarations documentation: If a comment in the first or second line of the Python script matches the regular expression coding[=:]\s*([-\w.]+), this comment is processed as an encoding declaration; the … Read more
You don’t need to encode data that is already encoded. When you try to do that, Python will first try to decode it to unicode before it can encode it back to UTF-8. That is what is failing here: Just write your data directly to the file, there is no need to encode already-encoded data. If you instead build up unicode values instead, you would … Read more
without using a computer you can calculate it like this: 0xFFFF FE58 is a negative number in 2’s complement. To get the absolute value you have to invert all bits and add 1 in binary. You also can subtract this number from the first number out of range (0x1 0000 0000) now we know that your … Read more
This way of specifying the encoding of a Python file comes from PEP 0263 – Defining Python Source Code Encodings. It is also recognized by GNU Emacs (see Python Language Reference, 2.1.4 Encoding declarations), though I don’t know if it was the first program to use that syntax.
You report three separate problems. This is a bit of a guess into the blue, because there’s not enough information to be sure, but you should try the following: input encoding: As suggested in comments, try “utf-8-sig”. This will remove the Byte Order Mark (BOM) from your input. double quotes: Among the csv parameters, you specify quoting=csv.QUOTE_NONE. This tells the csv library … Read more
